fullsize Invasion - 1969 Kaiser M715 - Photo 16

There’s a reason why that black smoke is visible in this image. It’s because this ’69 Kaiser M715, owned by Kevin Mackie of Milpitas, California, has been fitted with a biofuel-capable 7.3L Power Stroke turbodiesel engine. But wait there’s more. Like a Dana 60 front axle, Ford 10.25 rear axle, and bobbed frame and cargo bed. We’ll have a full feature on this incredible owner-built rig in an upcoming issue of Four Wheeler.
